brickman7713 Posted April 8, 2019 Share Posted April 8, 2019 A metal bowl with a weight of 1.35 N is placed in a larger kitchen container filled with corn oil. How much corn oil must the bowl displace in order to float? For reference, the mass density of corn oil is about 900 g/liter and its weight density is about 8.82 N/liter. Please give your answer in liters. Link to comment Share on other sites More sharing options...

Initial questions to start a discussion: -Have you solved similar problems where solids are (partially) submerged in water? -Are you familiar with Archimedes' principle? It might also help to draw a picture. Link to comment Share on other sites More sharing options...

It might help to take a look at the units. Oh I get it, it's just the weight of the displaced liquid divided by the weight density. Am I allowed to post the answer like that here?

As far as I know it is ok to post an answer ones own question in homework section, but it might be best to consult the rules first.
